Problems that UV ink should pay attention to in storage management
Ink is an important material for printing packaging materials. It displays the patterns and characters on the substrate by printing. The ink includes main components and auxiliary components. They are evenly mixed and repeatedly rolled to form a viscous gel fluid. It is composed of pigments, binders and additives. It is used for printing on books, periodicals, packaging and decoration, architectural decoration, etc. With the increase in social demand, the variety and output of inks have also expanded and increased accordingly.
The main components of ink: color material, connecting material
Ink auxiliary components: filler, thinner, anti-crust agent, anti-offset agent, slip agent, other additives
The ink should pay attention to the following problems during storage and management:
1. Safety first, keep ink away from fire and heat as much as possible to prevent accidents.
2. It is best to maintain a constant temperature in the ink warehouse, and the temperature difference with the printing workshop should not be too wide. If the temperature difference between the two is large, the ink should be put into the printing workshop in advance, which is not only conducive to the stability of the ink performance, but also ensures the high efficiency of production.
3. In some areas in the north, the winter is relatively cold, so you should avoid storing the ink outdoors to prevent the ink from gelling at low temperatures. If gelation occurs, transfer it to a warehouse with high temperature or put it in hot water to restore the insoluble matter to its original state.
4. In the storage and management of inks, the principle of "first in, first out" should be followed, that is, the ink purchased first is used first, to prevent the ink from affecting its use effect due to long storage time.
5. The ink also has a certain shelf life. If it is stored for too long, various components in the ink will separate and precipitate. Therefore, the ink should not be stored for a long time, and the general storage period is one year.
6. After printing, the remaining ink must be sealed and stored in a dark place. Before reuse, it must be filtered with a filter mesh of more than 100 mesh, and then mixed with new ink after fully stirred.
